While Nijin and Det were talking on the road, Nijin asked Det how to get to his old boss. Det said that there was a road of worlds to get there and they had to travel this road.
Nijin then decides to hit the road and they both set off together. Once they pass through the gate of time and space, they reach the first planet. On this planet, the sky is blood red, the ground is red, and the sun is red.
All things are red and Nijin is surprised by the strangeness of this planet. They see the natives and they look like an army. They go up to them and ask them questions about their journey.
Nijin says that they are on a journey to get the boss's head, and the army pretends to be the boss's employees. Suddenly, when Nijin and Det are surrounded, they realize that they are enemies and after making the first move, Nijin quickly takes out his sword to defeat them.
The commander of the army realizes that they will be defeated and eats the souls of the living and becomes stronger. Nijin's sword strike is easily stopped. Nijin and Det decide to do teamwork. While he stops Nijin's swords, Det continues to strike and so they continue.
The commander of the army starts to get tired and because he uses the power of the souls he eats so much, the souls he eats melt and melt his soul as well. Then, Nijine begs and says she doesn't want to die. Nijin will help on one condition: He tells me where the boss of this world is. The commander of the army shows the boss where he is and Nijin understands.
Nijin says with one condition: "Where is the boss of this world?" The commander of the army shows the direction with his hand and says, "If you go from this direction, you will find it." Nijin understands and freezes the man's soul with ice magic. The man's movements will slow down, but he will not die.
Nijin and Det discover that the commander of the army has a secret trump card, and as they leave, he pulls out a gun from behind his back. However, this is not a normal gun and it fires a very powerful laser bullet. Nijin knew he would do this and shoots the army commander.
He wasn't firing the gun and by shooting it multiple times he sank himself. Det is surprised and asks "What did you do?" he asks. Nijin explains: "While I was freezing his soul, I saw that gun and added a seal to his soul. If he held the gun and fired it, his soul would explode and it happened as I said."
Nijin and Det find the place pointed out by the army commander, and there is a guard in front of the door: The dragon is of the human species, twice as big as a normal human, and has a spear.
Nijin senses the dragon man's anger and says, "If you come close here, you will die." They continue walking and the dragon swings his spear as the human continues to fly quickly. Nijin also takes action and takes out his sword. The spear and sword collide and everything around begins to crumble.
Nijin can't stand it anymore and the dragon man's spear hits him and throws him into the tree. Nijin starts running and tells Det, "We're doing that." Previously, they developed the fusion technique for emergencies: Both bodies merge and become a stronger body. The name of this form is Nidet, and Nijin's swords also evolve, because they are connected to Nijin.
The human dragon is repulsed by Nijin's sword and is easily cut down. However, because they used the Fusion technique for a long time, their bodies are separated from each other. Just as he passes through the door, Nijin's phone rings.
